The following quotation is from the presentation at the above mentioned
site:

"
Until now we have discussed the absorption or the emission of a photon,
when the photon?s energy corresponds to the energy difference of two
molecular levels. But when a photon collides with a molecule other
processes may occur ? the photon may be scattered and changes its
direction of motion. If the photon?s energy is conserved (no change of
frequency) the process is termed Rayleigh scattering (after John William
Strutt Baron Rayleigh (1842-1919)). However, the molecule during the
interaction may capture some of the photon?s energy, or some may be
transferred to the photon. Consequently, due to this inelastic
collision, the photon emerges with a different energy ?
"

Oh, you sly so-n-so Ralph.
In the quote above, you stop just short of the name of the second process
(did you think I was incapable of clicking on a link and reading it myself).

The above quote should end ...

"... Consequently, due to this inelastic collision, the photon emerges with
a different energy, the Raman process (after Sir Chandrasekhar Venkata Raman
(1888-1970), the first Asian to win a Nobel Prize, in 1930)."

And yet on Jan 26 of this year, in the thread "TIRED LIGHT [ = NO BB ]" when
I asked you specifically ...

"As far as I can tell, no such experiment exists (Might you mean "Raman
scattering"???)."
- John Zinni -

Your responses was ...

"No."
- Ralph Hertle -

Any comment Ralph???


The "Rayleigh scattering" experiments and documentation are the general
area to investigate. The complete documentation would be of interest.

The elastic back-scatter experiments are not as interesting as the
photon-hydrogen inelastic collision experiments referred to above
regarding photon energy levels.
